Mac OS X Leopard (PPC and Intel) and Snow Leopard (Intel only) requires one of the latest versions of Ashlar-Vellum CAD and 3D modeling software to run effectively. You must have one of the following:

Graphite v8 SP3r0 (build 881) or later

Cobalt, Xenon or Argon v8 SP2r5 (build 873) or later

Does Ashlar-Vellum CAD & 3D Modeling Software Support FEA?

Graphite CAD software exports to 2D FEA programs using DXF. Cobalt, Xenon or Argon 3D modeling software exports to 2D or 3D FEA using SAT, X_T, STEP, IGES , DXF or STL. Finite Element Analysis is a serious science best left to professionals using something more than the “light” FEA features built into some competitive CAD packages.

Ashlar-Vellum CAD & 3D modeling software does not generate g-code but will easily transfer to a program that does. All CAM software will read one or more of the file types exported from Ashlar-Vellum software.

I want to run my old Vellum software on my new operating system.

It is technically impossible to provide “forward compatibility” for software that was purchased before a particular operating system was in existence. Ashlar-Vellum does provide limited consulting services to assist you in sometimes getting old software to run on new computers, however, the least expensive solution is to simply upgrade the software and avoid hours of headache.
